Rectus sheath hematoma is an uncommon entity of the anterior abdominal wall and an unusual cause of painful abdominal mass. Rectus sheath hematoma have been in association with trauma, infections, debilitating disease, collagen vascular disease, pregnancy. and the puerperium. Sudden disruption of a deep epigastric vessel may result in an abdominal wall hematoma, which depending upon its location and size, can produce symptoms and clinical findings compatible with a variety of acute intra-abdominal conditions. Such hematoma are infrequently encountered and early accurate diagnosis could prevent surgical intervention. Unfortunately, the clinical manifestations of rectus muscle hematoma are sometimes so dramatic that laparotomy is performed under the belief that intra-abdominal pathology is present. The diagnosis was confirmed at surgery in both patient. We present two cases of rectus sheath hematoma which were diagnosed by clinical & ultrasound examination preoperatively.

Vaginal Brenner tumor is extremely rare. Only five cases have been reported in the English literature to date. Here we report a vaginal Brenner tumor in a 76-year old postmenopausal woman, who presented with a 2.5cm-sized sessile vaginal polyp. Microscopically, it showed characteristic features of Brenner tumor consisting of three components; transitional islands, glands, and dense fibrous stroma. The epithelial tumor cells were positive for GATA-3, p63 and ER, but negative for PAX8. The origin of Brenner tumors in the vagina is unclear, but previous reports suggested of Müllerian origin. However, our case revealed that vaginal Walthard nests could be possible precursor lesions based on their immunohistochemical staining results.

Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

Trichomonas tenax(T. tenax) and Trichomonas hominis (T. hominis) were collected, cultured and sampled for comparative microscopical studies using electron microscope. Both flagellates were oval in shape and surrounded by a distinct outer membrane. Five recurrent flagella and one anterior flagellum had, each, 9 paris of peripheral and 1 pair of central fibrils, Undulating membrane was curved over the recurrent flagella, and bended in the middle at right angles with cell surface. Cytostome, engulfing bacteria, was observed in T. hominis. In the cytoplasm, there were fine dense glycogen particles, and vacuoles containing ingested materials. Dense pigment rods were also observed in both flagellates, but the rods were not distributed around the vacuoles in T. hominis. In T. tenax axostyle appeared as a cup-shaped structure comprising a single row of 41 fibrils, each about 120 a in diameter. It enclosed glycogen particles, and the open side was faced to the nucleus. Endoplasmic reticulum was observed around the nucleus, but it was less developed in T. hominis. Nucleus was ovoid having double nuclear membrane, which was clearly defined in T. hominis. Blepharoplast, parabasal body, Golgi appartus and mitochondrion was not observed in both flagellates.

BACKGROUND: The aim of this study was to assess demographics, clinical outcomes, and complications of classic floating elbow in adults. METHODS: Six patients with ipsilateral diaphyseal fractures of the humerus, radius, and ulna were reviewed retrospectively. All patients were treated operatively and available for follow-up at a minimum of 1 year after surgery. The average age of the patients was 45.2 years (22-64 years) and the average follow-up period was 37.0 months (14-103 months). They were evaluated with postoperative outcome measures, including a visual analog scale (VAS) for pain, Mayo elbow performance score (MEPS), and American Shoulder and Elbow Surgeons (ASES) shoulder score. Residual complications were also evaluated. RESULTS: Five patients (83.3%) had open fracture, and 4 patients (66.7%) presented with associated nerve injury. All fractures were united within postoperative 4 months, except 1 delayed union. The average VAS pain score, MEPS, and ASES shoulder score at the final follow-up examination was 2.5, 79.8, and 67.5 respectively. Three patients including 2 cases of joint stiffness with incomplete recovery from nerve injury and 1 case of complex regional pain syndrome had poor clinical outcome. CONCLUSIONS: Although the classic floating elbow is rare, these injuries potentially have associated problems such as open fracture or nerve injury. The presence of residual neurological symptoms predispose to poorer clinical outcomes.
